BRICK-HOLDER.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed December 21, 1915. Serial No. 68,107.

To all whom it may concern Be it known that I. EDWIN J. HART, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Brick-' Holders, of which the following is a specification.

My invention relates to improvements in brick holders, the object of the invention being to provide a tool which is adapted for positioning fire brick between boiler tubes, and which securely holds the brick yet permits it to be released when in position.

A further object is to provide a tool of the character stated which securely grips the brick regardless of irregularities in the surface thereof, and which is especially adapted for use in connection with :a spreader to hold the tubes apart while the brick is positioned between them.

With these and other objects in View, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a broken view in elevation illustrating my improved brick holder positioning a brick between boiler tubes. Fig. 2 is a view in side elevation of the brick holder shown in Fig. 1. Fig. 3 is a view in section on the.

line 33 of Fig. 1, and Fig. 4 is a fragmentary view in section on the line 4-4 of Fig. 1.

1 represents boiler tubes and 2a fire brick having recesses 3 in its sides and recesses 4 in its ends to receive the boiler tubes 1.

My improved brick holder comprises a bar 5 to which a lever 6 is pivotally connected by a rivet 7. The pivotal connection of the lever 6 with bar 5 is midway between the ends of said bar 5, and at the ends of the bar 5, tongues 8 are projected and project at right angles to the bar. These tongues 8 project into the recesses 3 of brick 2, and conform more or less in shape to the shape of the recess. The bar 5 is of such a length that the tongues 8 have a certain amount of play so that the bar can be readily placed in position on the brick and removed when desired. 1

The pivotal movement of lever 6 in one d r c i n l m ted by an arm 9, This arm 9 has a tongue 10 at its free end engaging the side of the'brick, and atits opposite end is formed with an H-shaped slot 11 through which a headed stud 12 on lever 6 projects. The shape of this slot 11 permits the parts to be adjusted so as to vary the length of the arm relative to the lever, but in most cases little orv no adjustment is necessary. The lever 6 is provided at its free end with a block 13 in which one end of a tube 14 is secured. This tube 14 houses an angular rod 15 which projects through an angular opening 16, in the end of the tube. ;A knife edge block 17 is secured on the end of rod 15 by means of a pin 18, and it will be noted particularly by reference to Fig. 1, that the connection of the block 17 with rod'15 is a somewhat loose one so as to permit of a certain amount of independent movement of block 17 to position itself on the edge of the brick 2. V

The free end of tube 14 is externally screw-threaded as shown at 19, and a casing 20 of general cylindrical form, but preferably tapering at its upper end, is internally screw-threaded as shown at 21 to engage the screw-threads 19 of tube 14. The rod 15 projects into the casing 20, and on its screw-threaded end 22 is provided with a nut 23. The movement of this nut is limited by an annular shoulder 24 in the casing 20, and by a cross pin 25, so that the rod is held against appreciable longitudinal movement, hence the movement of the casing 20 on tube 14 does not impart a rotary movement to rod 15, but causes the same to move longitudinally so as to force the block 17 into engagement with the brick, or release it therefrom. As I make the rod 14 of considerable length, I am enabled to manipulate the brick holder from a distance, and can easily release the holder from the brick by turning the casing 20 and rod 15 to draw block 17 away from the brick after the latter is in position between the boiler tubes. With my improved brick holder, the tongues 8 on bar 5 are caused to engage the walls of recesses 3 by a longitudinal pull on lever 6. The arm 9 limits the pivotal movement of the lever, and the block 17 exerts a longitudinal pulling action on the lever to bind by turning the casing 20, the pressure of all parts engaging the brick is released, and the brick holder can be quickly removed.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A brick holder of the character de scribed, comprising a bar having tongues at its ends adapted to engage opposite sides of the brick, a lever pivotally connected to the bar, and means on the lever engaging the brick, substantially as described.

2. A brick holder of the character described, comprising a bar having tongues at its ends adapted to engage opposite sides of the brick, a lever pivotally connected to the bar, and an adjustable block on the lever adapted toengage the brick, substantially as described.
